This is where the Jupiter Jack can come in handy. The Jupiter Jack is a small device that allows you to use your cell phone hands free while driving. One of the first things I noticed about this convenient device is that it is much simpler to use than expensive blue tooth wireless systems. The price is really easy on the pocket book too. It works with any type of cell phone by transmitting the signal to your car radio. You get clear sound quality as loud as you need it to be to hear over traffic, while still being able to see the road and hear surrounding noise. Jupiter Jack is small, light, and very portable. Using it is as easy as just plugging it into the cell phone. This is a fantastic product with a great price. Not only does it make talking on the phone while driving more convenient, it makes it a lot safer too.
